I thought Its becuase I was 开发者_如何学编程not admin on that machine and got that error. but then I used an admin account and got the same error. Any idea what could be the reason.

Run your process elevated. Right click -> Run as administrator.

sc create <MyServiceName> binPath= <PathToServiceExe>

You will need to execute this command from elevated cmd window.
